=SUMIF(CHILDREN(Status3), "Rejected", CHILDREN())
1) How do you use the NOT logical expression in a SUMIF statement to add values together only in those rows whose value does NOT have a certain string? For example, add all of the cost values together unless the status says "Rejected".
2) For the condition test range of the SUMIF Statement, when referring to children under a given column, do you have to use the row number? Trying to figure out why I need to use Children(Status3) instead of Children(Status).
Man, I wish this had an expression builder. I'd pay extra for it.
